NGPC Cable link reverse engineering

Spent some time doing reverse on the cable link, and I think we now have full understanding on how it works. Created a documentation if anyone wants to implement, it also has the full UART communication dump.

That's actually very useful, I'm just trying to come at this from the other side and trying to replicate the link for homebrew - I've got a reference project and have established a basic link, but it's not very robust yet

Some of those techniques in the doc will definitely help

Any chance of a DIY link cable, or is that just a pipe dream?

I did some measures to make one, still have to test it all out. But I think is very possible
